It has long been determined that the most effective measure against corrosion on an underground pipeline is to isolate the metal from contact with the surrounding earth or environment. This is best accomplished by the use of a coating as the first line of defense. For this coating to completely effect a means of stopping corrosion it would have to do the following:

  1. Stop the flow of electrical currents by being an electrical insulator.

  2. Be a continuous, holiday free coating after handling and installation.

  3. Maintain this perfect state without deterioration from mechanical, chemical or other forces.
